Summary
The purpose of this trial is to determine if rash caused by erlotinib can be successfully treated and if so to determine the optimal treatment approach.
Hypothesis:
Hypothesis 1: If the incidence of rash is 50% while on erlotinib, prophylactic monotherapy with minocycline can prevent occurrence in 50% of these patients.
Hypothesis 2: Treatment of rash is successful in improving rash by at least one Grade in 80% of patients.
Hypothesis 3: In patients with untreated rash, the rash will be self-limiting in 25% of patients, and 65% will be grade 1, 2A, and 2b. Ten percent will be grade 3 requiring treatment with monotherapy intervention.
Eligibility Criteria
Inclusion Criteria
- Histologically or cytological documented diagnosis of inoperable, locally advanced, recurrent or metastatic (stage IIIB or stage IV) non-small cell lung cancer.
- Evidence of disease (measurable disease is not mandatory).
- 18 years of age or older.
- ECOG performance status of 0 - 3.
- Written informed consent prior to study-specific screening procedures, with the understanding that the patient has the right to withdraw from the study at any time, without prejudice.
Exclusion Criteria
- A history of another cancer other than basal cell carcinoma or cervical cancer in situ within the past 3 years
- Prior therapy with any type of cancer growth factor inhibitor (EGFR inhibitor or agent targeting this family of growth factor receptors)
- Life expectancy of less than 12 weeks.
- Ongoing toxic effects from prior chemotherapy.
- Pregnant or lactating women.
- Females of childbearing potential who have a positive or no pregnancy test (pregnancy tests must be obtained within 72 hours before starting therapy). (Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-childbearing potential).
- Male or female patients with reproductive potential who are unwilling to use effective and reliable contraceptive methods throughout the course of the study and for 90 days after the last dose of study medication.
- Ongoing treatment with any inhibitors or inducers of CYP3A4 activity
- Any unstable systemic disease (including active infection, grade 4 hypertension, unstable angina, congestive heart failure, hepatic, renal or metabolic disease).
- Any significant ophthalmologic abnormality, especially severe dry eye syndrome, keratoconjunctivitis sicca, Sjögren syndrome, severe exposure keratitis or any other disorder likely to increase the risk of corneal epithelial lesions.
- Unwilling or unable to comply with the protocol for the duration of the study.
- Patients who have experienced prior hypersensitivity reaction to active ingredients or excipients of the following compounds: erlotinib, minocycline, tetracycline, doxycycline or clindamycin.
